I love my Leupold Mark IV Extra High rings, but if I had to do it all over again...I'd seriously consider the Burris Extreme Tactical X-High rings.
They are right in your $50-$60 price range and half the price of my Mark IV's and they are getting great reviews by guys running $1500-$3000 scopes.

A little expensive, but no loss of zero if you pull it off, and put it back on. Good scope=good mount. Bingo, Dual purpose AR!!
I run the extra-high burris xtr on all but one of my ar's. Work really good on cheek weld. Not to short that you have to smash your face down on the stock but high enough that you get a good solid cheek weld. The only one that I don't have the xtr's on is the one that I have an eotech with fts magnifier on. +1 on they don't break the bank.
